Zdravim,
potreboval by som poradit.
Priklad (jeden blok v subore):
$------------------------
NAME='ALFA'
CODE='x'
$------------------------
Takychto blokov je v subore vela s roznymi menami a kodmi. Potrebujem
naprogramovat skript ktory prehlada cely subor a najde vyrazy s menami
ALFA a podla toho co za kazdou ALFOU bude nasledovat (napr. x,y,z)
zmeni meno ALFA na BETAx,BETAy, BETAz a zemeneny subor ulozi.
Dostal som sa k tomu ze najdem vsetky vyrazy ktore potrebujem, podla
kodu zmenim meno na BETAx,y alebo z ale uz neviem ako zapisat nove
nazvy na rovnake miesto ako bola dana ALFA. Vzdy mi to zapise na
koniec suboru. Tu je moj kod.
Dakujem vopred za akukolvek pomoc.

NamFile="test2.nam"
BackupNamFile = 1

shutil.copyfile(NamFile,NamFile.replace(".nam",".nam.bak"))

LineNumArray=[]
ReqArray=[]
ReqName=""
NamFileOpen=file(NamFile,"r+")
for line in NamFileOpen:
LineTextFound1 = line.find("bk")
LineTextFound2 = line.find("_results")
if LineTextFound1 != -1 and LineTextFound2 != -1:
ReqName=line.split("'")[1]
print "Line: \t\t\t"+ str(LineNum)
